This patch fixes a bug in the AVR FRMIDX expansion logic.
The expansion would leave a leftover operand from the original FRMIDX,
but now attached to a MOVWRdRr instruction. The MOVWRdRr instruction
did not expect this operand and so LLVM rejected the machine
instruction.
This would trigger an assertion:
Assertion failed: ((isImpReg || Op.isRegMask() || MCID->isVariadic() ||
OpNo < MCID->getNumOperands() || isMetaDataOp) &&
"Trying to add an operand to a machine instr that is already done!"),
function addOperand, file llvm/lib/CodeGen/MachineInstr.cpp
Tim fixed this so that now the FRMIDX is expanded correctly into
a well-formed MOVWRdRr.
